In Vienna, a pilot project has been successful, in which scattering material was obtained from CO2. For example, exhaust fumes from cars can be used to remove ice from frozen pavements in a more environmentally friendly way.

The CO2 recycling technology called RemiCO2 was developed by the patent holder Hubert Lengheim together with the City of Vienna. The implementation was tested in the fire test hall of the City of Vienna’s testing, inspection and certification body (MA 39). With success, as the city announced in a broadcast. Within a month, 330 kilograms of CO2 could be bound. This corresponds to the CO2 emissions of a car on the Vienna – Oslo – Vienna route.
Use in sensitive areas
In the MA 39 hall, fire resistance tests are carried out, for example on walls, doors and ceilings. Carbon dioxide is produced during the combustion processes. In the new process, the CO2 is bound using a gas scrubber. This creates potassium carbonate – a spreading agent that is used in sensitive areas. For example, the city uses it near trees.
“As a de-icing and spreading agent, this secondary raw material is an environmentally friendly alternative to road salt and is also an important component in the production of fertilizers,” said Lengheim, founder and managing director of Allfull. For climate councilor Jürgen Czernohorszky (SPÖ), the successful pilot project is a step towards a waste-free city. “This project shows how circular economy can work in the construction industry.”
